Paluch is that act of one man initiating conversation in a public restroom. It is usually unexpected, unwanted conversation when at the urinal or in a stall. The act of being paluched is usually induced by the consumption of alcohol, thus the majority of paluching occurs in bathrooms inside bars or restaurants. However, similar instances occur at other locations, with the most awkward being that of that of the workplace (not necessarily induced by alcohol, as stated above.).

That man paluched me while I was minding my own business in the stall.
